Eisenberg-Lozano Goblet

So, I’ve been eying these two wine goblets/glasses for a while, and finally nabbed them for 18 bucks.

I’ve done a little research already, enough to know they were made by Eisenberg-Lozano, and are silver plated. The mark has Spain under it. Given the company [as far as I can tell] was only around for from 1953 to 1984, they had to have been made sometime between then. Minor damage and heavy tarnish has ensued from what I can gather was sheer neglect.

Here it is:

I am really hoping someone on this site can tell me an estimate of their worth, I haven’t even been able to look anything up online, because I can’t find anything on the company name or the goblets,
